Specific implementation mode
Principle according to the present invention describes a kind of compuscan and method, to the heart in ultrasound cardiac images
Dirty bending is corrected with transversely eccentered.Common straight line axis is plotted as the uniform intervals between chamber wall and prolongs from the apex of the heart
Reach the curve of mitral valve plane.It is transversely eccentered to reduce to generate shape evenly by stretching cardiac muscle in the picture.Make
It is these measures as a result, the boundary of the chambers of the heart is presented such that chamber wall is more equidistant and orthogonal with plane is checked so that energy
Editor is to indicate partitioning boundary and control in enough planes for creating more complete long axis MPR views and allowing lateral MPR planes
The more equidistant and orthogonal displacement of point.The long axis MPR views not shortened are generated, the view is cut by being bent the curve of axis
Piece.Now, editor control point will be operated more independent of other views in one of normal view, and be improved and drawn
The visualization and diagnosis at interface.
Fig. 1 illustrates three normal views and apical four-chamber (AP4) view of the heart that diagnosis carries out, three chambers of the apex of the heart
(AP3) view and two chamber of the apex of the heart (AP2) view.Top three width image a, b and c are the heart of diastasis, three width image of bottom
D, e and f is the heart of end-systole.The image analysis tool of such as Heart Model is Philips Healthcare
The part of (Andover, MA) ultrasonic system QLAB functions, can be according to volume (3D) data of heart automatically by these standards
View plane is divided into the MPR planes of delineation.As shown in Fig. 1, QLAB features can also be in ultrasound cardiac images from motion tracking
The boundary of heart, the boundary 210,212 and 214 of the left ventricle (LV) in such as these views and mitral valve plane 220.It is similar
Ground, can be directed to other features of heart, and such as right ventricle comes from motion tracking boundary.
Three normal view planes are at the public axis of LV with about 0 °, 60 ° and 100 ° of relative rotation angle phase each other
It hands over.Two intersections in normal view plane are illustrated in Fig. 2 a, wherein the LV planes in the AP4 views delineated at 210
It is shown as intersecting with the LV planes for the AP2 views delineated at 212 at axis 200.Line 222 is also shown in Fig. 2 a,
Laterally (short axle) view plane can be redeveloped into MPR images according to volumetric image data for instruction.Due to all these two dimension views
Plane is all extracted from same volume image data, so their cardiac silhouette can be organized as three-dimensional left ventricular cavity
The grid or frame electrode of room, as shown in Figure 2 b.The point that different boundary trace intersects each other marked in figure be, b, c.To the greatest extent
Pipe Fig. 2 a, which draw, indicates ideal situation, but in fact, 3D rendering data may not exclusively be easy to all border traces of automatic identification
210, the entirety of 212,232,234 and 236 (and other), or will not at least diagnostician be made to be entirely satisfactory.Therefore, QLAB
Diagnostic imaging program creates control point around the boundary drawn automatically, doctor can with control console with relative to image again
Position border trace.When the pointer device of doctor's utilization such as trace ball or mouse pulls in view plane or move control point
When, border trace will be moved into the new position with control point, but still glossily be connected to neighbouring control point, and process is known as
" elastic connection (rubberbanding) ".In figure 2b, intersection point a, b and c may be used as the control point of the border trace of diagram.
However, if control point is positioned as leaning on too close each other, it will appear problem.In this case, BORDER PROCESSING program without
Method smoothly repositions the border trace of connection.Instead, when doctor attempts mobile control point, trace can jump and become
It is unstable.In addition, when control point is too near to together, attempting the repositioning control point in a view plane can influence separately
The position of trace and control point in one view plane.As shown in Fig. 2 b, the boundary of different views plane by they with
The relationship of public 3D rendering data set and it is all spatially interrelated.Therefore, it is intended that control point tool it is well-regulated uniformly between
Every so that the unstable of trace will not be led to or influence the border trace in other view planes and control by editing their position
Point.
Longitudinal straight and symmetrically cardiac image is usually not in these editor's problems.Fig. 3 a illustrate longitudinal flat
The cardiac muscle 60 of straight and symmetrical heart.It is automatic between the apex of the heart 230 of heart and the center of the mitral valve plane 220 of the bottoms LV
The axis 200 of drafting is downward along the central line of LV chambers.Flat view plane across straight axis 200 will capture LV's
The complete long axis view not shortened.When creating the transverse views plane 222 orthogonal with axis 200, symmetrical cardiac muscle 60 will be in
It is existing roughly circular, as shown in the right side of Fig. 3 a.When the control point position line 202 of homogeneous angular distribution is positioned as originating from axis
When 200, the intersection with heart wall generates equally distributed control point a, b, c, d and e.In addition, it is seen that position line orthogonally with
Cardiac muscle intersection.This generates the short paths 204 by endocardial border and cardiac muscle, are useful for measuring correct myocardial thickness, such as
What item 206 illustrated.
However, not all heart is all the ideal form of this image analysis.Fig. 3 b are illustrated with bending
The cardiac muscle 60 of the heart of longitudinal shape, i.e., so-called banana heart.When axis 200 the apex of the heart 230 and mitral valve plane 220 it
Between be drawn when, it can be seen that it is closer to the left side of heart and further from the right side of heart, as shown in the figure.As shown,
The transverse plane 222 of orthogonal positioning will appear in right side, wherein axis 200 is close to the left side of heart and far from right side.When
When control point position line 202 is plotted as originating from axis 200, heart is not generally evenly distributed in the point of the intersection of cardiac muscle 60
In surrounding.Control point b, c and d wide apart, and point a, f and e draw closer together much.When doctor attempts to reposition control point f
When, it can result in unstable and reposition adjacent point a and e unintentionally.In addition, position line 202 not orthogonally with
Heart wall intersects, but intersects at different angles.The measurement result of endocardial border and myocardial thickness be distorted and inaccuracy,
As shown by the sloped position line chart of the item 206 on right side in figure.
Fig. 3 c illustrate following situation：Myocardium not instead of buckling is as shown on the right more oval in the horizontal
Shape rather than it is circular.The ellipse of cardiac muscle causes control point a, b and d, e too close, and control point c and f are adjacent thereto
Control point segmentation it is too wide.Although level control points position line intersects with cardiac muscle 60 in an orthogonal manner in short axis view,
The intersection for being other position lines 202 is not orthogonal, again lead to cardiac muscle along position line thickness be distorted, as shown at 204 with
And shown in item 206.
Principle according to the present invention mitigates these problems by drawing bending axis 200 as shown in Figure 3d.Such as Fig. 3 d
Shown, axis 200 is not plotted as the straight line between the apex of the heart 230 and mitral valve plane 220 instead of, as equal in view plane
The curve being located in evenly between the opposite side of heart.Curve may not follow strictly cardiac anatomy, but can pass through
Image processing software smoothly turns to smooth curve, rather than zigzag and fast-changing curve.For this smooth curved
Axis, conic model are preferred.As a result it is illustrated by the smooth middle axial curve 200 on the left of Fig. 3 d.Compared with Fig. 3 b, in bending
Axis makes the orthogonal lateral shaft plane of delineation have axis 200 more placed in the middle, from its evenly spaced control point position line
202 more orthogonally intersect with the cardiac muscle in short axle, as shown in the right side of Fig. 3 d.This will create at such as 204 and pass through 206 institute of item
The more orthogonal path of the cardiac muscle shown, accurately indicates true myocardial thickness.According to another aspect of the present invention, by using
Image processing software " stretches " cardiac muscle and reduces any bright of the cardiac muscle in short axis view to generate more round shape in the picture
Aobvious elliptical shape, as indicated by the arrow on the right side of Fig. 3 d.The orthogonal affine stretching of center line for the image procossing and
Speech is preferred.When both modifications of application, the transverse views of heart and its cutting planes show as the reason of more similar Fig. 3 a
Think the transverse views of heart shape, and will realize the dirty measurement result those of sought closer to diagnostician.
Due to checking that medium is flat-panel screens for ultrasonic system, by 3D rendering data sampled with
The curve slice across bending axis is generated, curved images are then stretched into flat surfaces to show, long axis view
The benefit of middle bending shaft is most preferably presented to diagnostician.Therefore, when displayed, axis can be shown as straight line by final image.It is logical
Cross the result for the flexible deformation for checking that the image of Fig. 4 and Fig. 5 can be appreciated that the plane of bending intersected with bending axis.In Fig. 4
In, as discussed in cardiac image a, b and c, the axis 200 in the anatomy correct images of LV has been bent above.When
Flexible deformation is performed so that the plane of bending defined by bending axis 200 to be considered as in the plane of ultrasound system image display
When flat surfaces, LV is shown as respectively as shown in Fig. 5 a, b and c, wherein axis is shown as straight line.As shown in image, Fig. 5's
The boundary and area of LV in processed image is more irregular, and makes it easier for diagnosing and measure.
Diagnostician recognizes that the processed image of Fig. 5 is anatomically correctly schemed by what ultrasonic system acquired
Picture, but be treated as being easier to diagnose and measuring, this is important.According to another aspect of the present invention, ultrasound of the invention
System can generate the animation for becoming the image that bending has been straightened from the image with bending axis image, as shown in Fig. 6
's.Image on the left of Fig. 6 is the image of Fig. 4 a, wherein axis has been plotted as being uniformly positioned in the correct LV's of anatomy
Curve between opposing sidewalls.Image on the right side of Fig. 6 is the image of Fig. 5 a, by bending axis MPR plane deformations for straight plane and
It generates.Intermediate image between the left end and right end of Fig. 6 shows the two images that the progressive sequence stretched with axis generates.
When these images (and other images) are used as animation sequence by image processing software to be demonstrated to diagnostician, doctor can be with
The image processing effect on the original image of left side is easily grasped, and observes it is how to be changed to the more convenient diagnosis on right side
But anatomically less accurate image.
As explained for left ventricle, the disclosure can be used for other chambers of the heart, such as right ventricle (RV).Fig. 7 A and 7B
Show the example using bending MPR planes for bending right ventricle.AP4 views in Fig. 7 A are shown as identified as dotted line
Three MPR planes, the referred to as straight MPR apexes of the heart 1 (SMA1), the straight MPR apexes of the heart 2 (SMA2) and the bending MPR apexes of the heart 1 (CMA1).SMA1 quilts
It is positioned at the center of tricuspid valve (TV), and is also orthogonal to AP4 view planes and short-axis view plane (SAX).Herein, SMA1 causes
The shortening view of RV chambers.Alternatively, SMA2 can be oriented as the apex of the heart across TV and RV, but the view also results in RV
The shortening of chamber or the view of inaccuracy.As shown, it is similar with above-mentioned LV analyses determine CMA1 uniform planes be located in
Between the wall of right ventricle and include tricuspid valve and the apex of the heart of RV.
Fig. 7 B show the cutting line of the short axis view of right ventricle and AP4 views in Fig. 7 A.Similar to SMA1 and SMA2
The problem of, the MPR planes for being identified as straight MPR short axles 1 (SMS1) are located in the center of right ventricle, but the phase cannot wear completely
Cross crescent RV.On the contrary, bending MPR planes, bending MPR short axles 1 (CMS1) are located at the axis of RV, in short axis view
See, and it is across each tip of crescent RV.
Fig. 8 shows constructed according to the invention there is bending axis as described above and less oval transversal for handling
